We have too many "rsrc" around which makes the name of struct
io_rsrc_node::rsrc_list confusing. The field is responsible for keeping
a list of files or buffers, so call it item_list and add comments
around.

We use ->rsrc_ref_lock spinlock to protect ->rsrc_ref_list in
io_rsrc_node_ref_zero(). Now we removed pcpu refcounting, which means
io_rsrc_node_ref_zero() is not executed from the irq context as an RCU
callback anymore, and we also put it under ->uring_lock.
io_rsrc_node_switch(), which queues up nodes into the list, is also
protected by ->uring_lock, so we can safely get rid of ->rsrc_ref_lock.

Currently, for nodes we have an atomic counter and some cached
(non-atomic) refs protected by uring_lock. Let's put all ref
manipulations under uring_lock and get rid of the atomic part.
It's free as in all cases we care about we already hold the lock.

io_free_req() is not often used but nevertheless problematic as there is

We cache refs of the current node (i.e. ctx->rsrc_node) in
ctx->rsrc_cached_refs. We'll be moving away from atomics, so move the
cached refs in struct io_rsrc_node for now. It's a prep patch and
shouldn't change anything in practise.

One problem with the current rsrc infra is that often updates will
generates lots of rsrc nodes, each carry pcpu refs. That takes quite a
lot of memory, especially if there is a stall, and takes lots of CPU
cycles. Only pcpu allocations takes >50 of CPU with a naive benchmark
updating files in a loop.
Replace pcpu refs with normal refcounting. There is already a hot path
avoiding atomics / refs, but following patches will further improve it.

The right place to add the debugfs create is in
setup_driver() and remove it in teardown_driver().
Current code adds the debugfs when creating the device but resetting a
device will remove the debugfs subtree and subsequent set_driver will
not be able to create the files since the debugfs pointer is NULL.

In verity_end_io(), if bi_status is not BLK_STS_OK, it can be return
directly. But if FEC configured, it is desired to correct the data page
through verity_verify_io. And the return value will be converted to
blk_status and passed to verity_finish_io().
BTW, when a bit is set in v->validated_blocks, verity_verify_io() skips
verification regardless of I/O error for the corresponding bio. In this
case, the I/O error could not be returned properly, and as a result,
there is a problem that abnormal data could be read for the
corresponding block.
To fix this problem, when an I/O error occurs, do not skip verification
even if the bit related is set in v->validated_blocks.

We normally clear the endpoint then unmap LUNs so the devices are fully
shutdown when the LUN is unmapped, but it's legal to unmap before
clearing. If the user does that while TMFs are running then we can end
up crashing.
vhost_scsi_port_unlink assumes that the LUN's tmf struct will always be on
the tmf_queue list. However, if a TMF is running then it will have been
removed while it's executing. If we do a LUN unmap at this time, then
we assume the entry is on the list and just start accessing it and free
it.
This fixes the bug by just allocating the vhost_scsi_tmf struct when it's
needed like is done with the se_tmr struct that's needed when we submit
the TMF. In this path perf is not an issue and we can use GFP_KERNEL
since it won't swing directly back on us, so we don't need to preallocate
the struct.

If vhost_scsi_setup_vq_cmds fails we leave the tpg->vhost_scsi pointer
set. If the device is freed and then the user unmaps the LUN, the call to
vhost_scsi_port_unlink -> vhost_scsi_hotunplug will see the that
tpg->vhost_scsi is still set and try to use it.
This has us clear the vhost_scsi pointer in the failure path. It also
has us take tv_tpg_mutex in this failure path, because tv_tpg_vhost_count
is accessed under this mutex in vhost_scsi_drop_nexus and in the future
we will want to serialize access to tpg->vhost_scsi with that mutex
instead of the vhost_scsi_mutex.

When the kernel is built without support for zoned block devices,
virtio-blk probe needs to error out any host-managed device scans
to prevent such devices from appearing in the system as non-zoned.
The current virtio-blk code simply bypasses all ZBD checks if
CONFIG_BLK_DEV_ZONED is not defined and this leads to host-managed
block devices being presented as non-zoned in the OS. This is one of
the main problems this patch series is aimed to fix.
In this patch, make VIRTIO_BLK_F_ZONED feature defined even when
CONFIG_BLK_DEV_ZONED is not. This change makes the code compliant with
the voted revision of virtio-blk ZBD spec. Modify the probe code to
look at the situation when VIRTIO_BLK_F_ZONED is negotiated in a kernel
that is built without ZBD support. In this case, the code checks
the zoned model of the device and fails the probe is the device
is host-managed.
The patch also adds the comment to clarify that the call to perform
the zoned device probe is correctly placed after virtio_device ready().

The merged patch series to support zoned block devices in virtio-blk
is not the most up to date version. The merged patch can be found at
https://lore.kernel.org/linux-block/20221016034127.330942-3-dmitry.fomichev@wdc.com/
but the latest and reviewed version is
https://lore.kernel.org/linux-block/20221110053952.3378990-3-dmitry.fomichev@wdc.com/
The reason is apparently that the correct mailing lists and
maintainers were not copied.
The differences between the two are mostly cleanups, but there is one
change that is very important in terms of compatibility with the
approved virtio-zbd specification.
Before it was approved, the OASIS virtio spec had a change in
VIRTIO_BLK_T_ZONE_APPEND request layout that is not reflected in the
current virtio-blk driver code. In the running code, the status is
the first byte of the in-header that is followed by some pad bytes
and the u64 that carries the sector at which the data has been written
to the zone back to the driver, aka the append sector.
This layout turned out to be problematic for implementing in QEMU and
the request status byte has been eventually made the last byte of the
in-header. The current code doesn't expect that and this causes the
append sector value always come as zero to the block layer. This needs
to be fixed ASAP.

Announce that the driver supports CAN_CTRLMODE_BERR_REPORTING by means
of priv->can.ctrlmode_supported. Until now berr reporting always has
been active without taking care of the berr-reporting parameter given
to an "ip link set ..." command.
Additionally apply some changes to function esd_usb_rx_event():
- If berr reporting is off and it is also no state change, then
immediately return.
- Unconditionally (even in case of the above "immediate return") store
tx- and rx-error counters, so directly use priv->bec.txerr and
priv->bec.rxerr instead of intermediate variables.
- Not directly related, but to better point out the linkage between a
failed alloc_can_err_skb() and stats->rx_dropped++:
Move the increment of the rx_dropped statistic counter (back) to
directly behind the err_skb allocation.

Devicetree changes for omaps for gta04, Phytec am335x devices, and to
drop a obsolete compatible property:
- A non-urgent fix for gta04 to enable more dma channels for some audio
configurations
- Update the dts compatible and vendor prefixes for gta04
- A series of updates for Phytec am335x based boards to configure more
devices like rtc and audio, and a few clean-up patches
- A change to drop the usage of "ti,omap36xx" compatible, the driver
code already checks for "ti,omap3630" that is also alread set in the
dts files. This makes the yaml binding conversion a bit simpler.

If CONFIG_CRYPTO=n (e.g. arm/shmobile_defconfig):
WARNING: unmet direct dependencies detected for RPCSEC_GSS_KRB5
Depends on [n]: NETWORK_FILESYSTEMS [=y] && SUNRPC [=y] && CRYPTO [=n]
Selected by [y]:
- NFS_V4 [=y] && NETWORK_FILESYSTEMS [=y] && NFS_FS [=y]
As NFSv4 can work without crypto enabled, remove the RPCSEC_GSS_KRB5
dependency altogether.
Trond says:
> It is possible to use the NFSv4.1 client with just AUTH_SYS, and
